Siemens 6ES7212-1AE40-0XB0 SIMATIC S7-1200 CPU 1212C DC/DC/DC 8DI/6DO/2AI PLC

The Siemens SIMATIC S7-1200 CPU 1212C (6ES7212-1AE40-0XB0) is a compact DC/DC/DC controller with 100 kbyte integrated work memory, 8 digital inputs, 6 digital outputs (4 usable as 100 kHz high-speed outputs), and 2 analog inputs onboard. It runs on 20.4 - 28.8 V DC and communicates over a single isolated PROFINET interface supporting IO Controller and IO Device operation.

Certifications & Standards

• CE mark
• UL approval
• cULus
• FM approval
• RCM
• KC approval
• Marine approval

Selection Notes

The 1212C's 8 DI / 6 DO / 2 AI onboard I/O count covers small machine cells without adding a signal module, sitting above the base S7-1200 CPU's fixed I/O while staying compact. Its 3 communication module slots support PROFIBUS or AS-Interface add-ons without occupying the onboard PROFINET port. Check the 100 kbyte work memory against the program size before selecting it over a larger CPU in the same family if the application is memory-intensive.

Applications

Serves as the central controller for compact machine cells, small conveyor or packaging skids, and standalone process skids where 8 DI/6 DO/2 AI onboard covers the I/O without an expansion rack.
